Wajik ketan hitam (Indonesian sticky rice cake) is a very simple and delicious dessert using only a handful of ingredients. This dessert uses both white and black sticky rice, and flavored with coconut milk and pandan leaves. It is dairy free, vegan friendly, and completely gluten free too. If you need to prepare an exotic dessert for your next gathering, you need to give this a try.
You can find sticky rice, or glutinous rice, in most Asian grocery. It comes in white and the dark purple/black color. Unlike other rice, they need to be soaked for a long time. A four hour soaking time is minimum, but overnight is best to ensure a soft rice.
Steaming the sticky rice
You will need a steamer to steam the rice. Since the rice grain will fall off through the steamer holes no matter how small the hole is, I suggest spreading some banana leaves. Not only will the leaves prevent the rice from falling through, it also gives a fragrant smell to the sticky rice. Typically I need about 45 minutes of steaming time to get my preferred rice texture. You can add or reduce the steaming time, but make sure you like the texture before turning off the steamer.
Making the wajik
Once the rice is out of the steamer, it is time to make the pandan flavored coconut syrup. Boil together coconut milk, sugar, salt, and pandan leaves in a sauce pot. Once the sugar has dissolved, add the steamed sticky rice into the pot, and stir until the sauce is absorbed by the rice. Transfer the rice into a saran wrapper lined mold (I use a loaf pan, you can use other mold of your choice). Gently pack the rice with a spatula, then cover the exposed part with even more saran wrap. Once it is completely cool, use an oiled knife to cut into serving sizes.
